TO ALL WHOM IT MAY CONCERN: l

VBe it known that I, (LA. HARPER, of Wheeling, in the county ofDelaware, and State of Indiana, have invented a new andimprovedCultivator; 'and I do hereby declare that the following is afull, clear, and exact description thereof, which willenable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which- IFigure 1 is a side view of my improved cnltivator.

Figure 2 is a front view Aof the same. o

Similar letters of reference indicate corresponding parts.

My-invention has for its object to furnish an improved cultivator, soconstructed and arranged as toremove the clods and rubbish in front ofthe plough, s'o that they may not be thrown against or upon the smallplants being cultivated, and which will enable the ploughs to be muchmore easily raised to pass over stumps and other obstructions, and to bemore easily transported from place to place; and it consists in thecombination' of a spiral or screw-plate and wheel with the cultivator orplough-frame, as hereinafter morel fully described.v

A is the horizontal frame or beams ot' the oultivator, B are theplougl1-standards, C are the ploughs, and D are the handles, about theconstruotionof whichparts there is nothing new.- D is a wheel, the 11x100f which revolves in bearings E attached to the framey orbeams A, Thewheel D should be of such a size as to roll along the ground while theploughs are working, and should -bo placed so far forward as not tointerfere with the working of the ploughs, allowing them to be run at agreater or less depth, as may be desired, and so that, by raising therear part of the cultivator, its weight may be mostly supported upon thewheel, for convenience in passing over or around stumps, roots, andother obstructions, Aand for convenience lin turning at the end of therows, and in passing from one field to another. To the side ofthe wheelD issecurely attached or upon it isformed a small bevel-gear wheel, F,theteeth of' which mesh into the teeth ofthe bevel-gear ,wheel Grattached to the forward end of the spiral or screwfplate H. The forwardcnd of the spiral plate H is pivotcd to one of the bearings E, or tosome suitable support attached to the frame A, and its rear end is'pivotcd to the plough-standard-B, or to an arm or other support attachedto the ploughLstandard B, orA to the plough C, or to both, in such aposition that, as the machine is advanced, it may brush away vthe clodsand'othcr rubbish from before'the plough, and thus prevent their beingthrown against or uponlthe smallplants, and alsoprevent the plough fromAbecoming choked. After the plants ,have become larger, so that they willnot be injured 'by the clods thrown aganst'them by the plough, thespiral plate .need not be used. i

It should be observed that` my improvement may be attached to acultivator having one, two, three, or any number of ploughs, with equalfacility and advantage. 5 v I Having thus described my invention, Iclaim as new, and desire to secure by Letters Patent- 1. The combinationof the wheel D with the cultivator-frame A, substantially as hereinshown and desi cribed, and for the purpose set forth.

2. The combination of the spiral orscrew-plate H with thewheel D', andwith the cnltivator-frame A B, ubstantially as shown and descfribed, andfor the purpose set forth.

The above s pecication of my invention signed by me, this 5th day ofNovember, 1867.
